In this series we address important topics for clinicians who participate in research or are considering research as part of their career path in emergency medicine. While much emergency research is successfully done by clinicians without a research higher degree (RHD), undertaking a master's degree or doctorate allows a research topic to be pursued in greater depth. It also provides a solid basis for a future research career in terms of research quality, advanced skills, academic progression and track record, as well as eligibility for grants and RHD supervision. The decision to undertake a RHD is not an easy one, and requires consideration of the time and cost involved, as well as the impact on a clinician's life plans. However, the expertise provided through a RHD often ultimately complements clinical training and establishes an excellent foundation for future research and career. This article provides an overview of RHDs and what to consider before embarking on one.
